The effect of cinnamon on A1C among adolescents with type 1 diabetes

OBJECTIVE - The purpose of this study was to determine the effect of cinnamon on glycemic control in adolescents with type I diabetes. RESEARCH DESIGN AND METHODS - Using a prospective, double-blind, placebo-controlled design, 72 adolescent type I diabetic subjects were treated in an outpatient setting with cinnamon (1 g/day) or an equivalent-appearing placebo for 90 days. AlC, total daily insulin intake, and adverse events were recorded and compared between groups. RESULTS- There were no significant differences in final AlC (8.8 vs. 8.7,P = 0.88), change in AlC (0.3 vs. 0.0, P = 0.13), total daily insulin intake, or number of hypoglycemic episodes between the cinnamon and placebo arms. CONCLUSIONS - Cinnamon is not effective for improving glycemic control in adolescents With type 1 diabetes.
